WATCH: Submarine sails into Portsmouth for rare visit

A MURDEROUS video released by terror group Isil has sickened the Muslim community of Portsmouth.

The chilling ten and a half minute video shows a British man – who intelligence sources have named as Abu Rumasayah – brutally executing an alleged British spy before threatening the UK with future terror attacks.

Then, in a depraved move, the terrorist’s propaganda recording shows a young boy, believed to be four-year-old son of the female British fanatic Grace ‘Khadijah’ Dare, threatening to ‘kill the kuffar’ (unbelievers).

Now a Muslim community leader from Portsmouth – who asked not to be named – has lashed out at the disgusting recording released by the Islamist extremist group.

‘It’s unspeakable. It’s really, really disgusting the things happening in that part of the world,’ he said.

‘It’s upsetting so many people. It’s against the religion and against the beliefs.

‘They’re not people – they’re not human beings. What they are doing is unspeakable.’

The video bares a resemblance to those recorded by Jihadi John – who was killed in an airstrike last year.

Prime Minister David Cameron described the latest video as a ‘desperate’ and ‘barbaric’ propaganda tool.
